How to do: Step 1. Get Universe sandbox if you don't have it. Step 2. Click New on menu and go on add and place earth somewhere. Step 3. Go onto Temperature (I think I can't remember T^T) And scroll down until you see "Freeze All". Step 4: Click "Freeze All then make the speed super fast and un pause the simulation. (Skip if already already moving and just click "Freeze All" but still make the speed fast.) Step 5. Make the time 4056 G years per second (Around 4 Trillion years per second) Then wait for around 10 minutes and come back. Then "Melt All" and "Freeze All." Step 6. Go onto the wrench and click "Material" And make it water and just make the mass of it like 1,000,000,000 or something. Around the size of Jupiter. Then throw it at the earth while time is on still high and it turns into a big Venus. Then throw more and it's this. (Most likely)
